68

70

72

75

the answer is 75 pounds

Rover will consume 75 lb of dog food in 60 days.

Step-by-step explanation:

The ratio 32 days to 60 days is equal to the ratio 40/x:

32/60 = 40/x

Cross multiplying, we get 32x = 60*40, or 32x = 2400

Then x = 2400/32 = 75

Rover will consume 75 lb of dog food in 60 days.
